he bars are'held in retracted position so as-not to interfere with the dropping of the articles onto the arms 20 by providing the bars 21 with shoulders 21 which drop behind .lugs on the guides when the bars are retracted. For releasing or unlocking the bars as soon as the desired number of mi;

In a device of the class described, the comation. with collecting device comprising a pair of connected, horizontally slidable bars, a pivoted lever associated with said bars to normally hold them in retracted position, said lever being operatively connected with said count- 'lng device, and a pair of swinging weights tending to slide said bars outwardly, Whereby upon delivery of a predetermined numberof articles the pivoted lever is automaticallyreleased by' the counting deviceand the bars-are slid horizontally. forward to interrupt the delivery of any more articles 'from the conveyer to the collecting device. p
